Abstract
A semiconductor element cooling structure includes a side wall provided on a downstream side of flow of cooling air in a cooling air passage, a plurality of cooling fins forming cooling air branch passages, and a plurality of cooling fins forming cooling air branch passages. The cooling fins each have an end portion at a tip extending toward the cooling air passage. A virtual line obtained by connecting the end portions of the plurality of cooling fins and a virtual line obtained by connecting the end portions of the plurality of cooling fins each have a gradient with respect to a direction of the flow of the cooling air in the cooling air passage which is greater on an upstream side of the flow of the cooling air in the cooling air passage than on the downstream side thereof.
